The mining team consists of approximately 140 employees. Mining is conducted via a company owned and operated mine fleet of drill, truck, excavators and other ancillary mining equipment. The operations commenced in 2019 as an open pit CIL operation with mineralized material produced from deposits in the Paloma and Martinetas regions which are mostly depleted of ready to mine resources. In 2023, MDN added a heap leach operation to process the mineralized material from Calandrias Sur open pit. The PEA is focused on the development and mining of the high grade Calandrias Norte open pit to be processed through the existing 1,000 tpd CIL plant until late 2024 and the ongoing operations and expansion of the Calandrias Sur heap leach operations until at least 2028. In addition, the PEA has envisaged the development of an initial small scale underground mining operation upon which future underground exploration is expected to extend the mine life; and the processing of low-grade mined material in the Martinetas area from several stockpiles.
